Does ATP Provide Energy?

When using standard thermodynamic values, the chemical reaction whereby ATP is converted to ADP is found to have a positive value for ΔG. This would imply the reaction REQUIRES energy. However, analyzing the process under physiological conditions shows that ΔG is in fact negative, as expected.

Drinking Dinosaur Pee?!

It has been claimed that because all water ultimately ends up in the water cycle, we drink water that the dinosaurs peed out. What does chemistry have to say about this assertion?

Seashell Chemistry

Placing dry ice in limewater is a great demonstration to accompany discussions on a variety of chemical topics, including the impact of ocean acidification on marine organisms that depend upon the formation of CaCO3.

Applying Chemistry Principles to COVID-19: Think-Pair-Share Questions

This post is comprised of questions (Qs) that challenge students to apply the knowledge acquired in their chemistry education to COVID-19. The questions encourage students to think across scientific disciplines, to think 'outside the box', and/or 'connect the dots'. Understanding how SARS-CoV-2 works inside the human body is every bit about chemistry as it is about biology as it is about physiology.
